why do i see so little research on this shit? isomer triggering has been PROVEN to be real the only current negative is we arent very good at triggering some of the isotopes with less energy than they release and the ones we can trigger with much lower energy are short lived. But there are HEAPS of isomers which haven't even been looked into (cadmium 113m im particularly interested in) sure it cant make a bomb but it definitely could make a nuclear powered jet engine
